What is a fish farm?

Fish farms are businesses that produce a limited number of fish for sale in restaurants and supermarkets. The business is called aquaculture, which includes the farming of fish, shrimp, shellfish, and seaweed. Fish can be grown in natural waterssuch as ponds, lakes, rivers, and streamsor artificial environments, like tanks, pools, and special cages. Fish species such as salmon, catfish, rainbow trout, tilapia, and cod grow in fish farms. Fish farms around the world supply almost half of the world's total food fish supply. The United States has fish farms in California, Idaho, Alabama, Arkansas, Louisiana, Mississippi, and along the southeastern U.S. coast. However, it imports about 85 percent of its seafood and half of these imports come from fish farms in Asia and Latin America.
